Cognitive psychology is an enormous field with a rich history. One problem confronting instructors in cognitive psychology courses is covering such diverse topics as pattern recognition, attention, memory, language, decision-making, and problem solving. It is virtually impossible to both cover these topics and provide details regarding the beauty of the experimental studies that have tackled important topics in a single textbook. Cognitive Psychology: Key Readings helps fill this void and provides students with the opportunity to learn about the details of the actual articles and chapters that have had major influences in the development of this discipline. The classic papers were selected because they have been central in defining distinct areas of research or changing the way researchers think about a given topic. The reader can learn about the available literature that motivated a study, the theoretical rationale, and the details of the methods and results that were used to develop a better understanding of the topic. In this way, the reader can learn about the actual science of uncovering the theoretical issues, instead of simple overviews of the results. In addition, because cognitive psychology is constantly evolving, introductory sections to each topic are provided to help the reader better understand why a particular study is so important to the field. Along with an overview chapter that provides introductions to theoretical and methodological approaches that cognitive researchers have employed, Cognitive Psychology: Key Readings will begin to appreciate how scientists are unravelling how the mind works.
